Test patterns
For test purposes, the ADC1412D can be configured to transmit one of a number of
predefined test patterns (via bits TESTPAT_SEL[2:0]; see
Table 27
). A custom test pattern
can be defined by the user (TESTPAT_USER[13:6]; see
Table 28
and
TESTPAT_USER[5:0]; see
Table 29
) and is selected when TESTPAT_SEL[2:0] = 101.
The selected test pattern is transmitted regardless of the analog input.

11.6 Serial Peripheral Interface (SPI)
11.6.1
Register description
The ADC1412D serial interface is a synchronous serial communications port that allows
easy interfacing with many commonly used microprocessors. It provides access to the
registers that control the operation of the chip.
This interface is configured as a 3-wire type (SDIO as bidirectional pin).
Pin SCLK is the serial clock input and CS is the chip select pin.
Each read/write operation is initiated by a LOW level on CS. A minimum of three bytes is
transmitted (two instruction bytes and at least one data byte). The number of data bytes is
determined by the value of bits W1 and W2 (see
Table 18
).
